Perinuclear and nuclear envelope localizations of Arabidopsis Ran proteins.
Article in Plant cell reports, 2007. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 17 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Using phragmoplastin-interacting protein 1 (PhrIP1) as bait, we isolated an Arabidopsis cDNA encoding Ran2, a small Ras-like GTP-binding protein. The interaction between PhrIP1 and Ran2 was confirmed by an in vitro protein-protein interaction assay with purified Ran2 and PhrIP1. The plant Ran2 shares high sequence homology, 78 and 86% at the amino acid level, with human Ran/TC4 and C. elegans Ran, respectively. Our results obtained from enzyme assays and Western blot analysis show that Ran2 has intrinsic GTPase activity and is present in the soluble fraction of Arabidopsis seedling extract. Fluorescent microscopy using anti-Ran2 antibody revealed that the Ran protein is localized in the perinuclear region with the highest concentration at the nuclear envelope. In contrast to its animal counterparts that are present in the nucleoplasm, the Ran protein is absent inside the nucleus. These results suggest that plant Ran proteins may be involved in mediation of nucleocytoplasmic transport and assembly of the nuclear envelope after karyokinesis in plant cells.
